🧠 Another Deep Dive into AI Security at BSides Luxembourg 2026

“Exploiting the Past: How Linguistic Redundancy Weaponizes the Quantum Search Landscape” – Alessio Di Santo & Gabriella Lanziani
Talk (40 minutes)

Step into a 40-minute talk where cryptanalysis meets quantum computing, uncovering how linguistic patterns from Renaissance texts can disrupt modern quantum search algorithms. This session explores how redundancy in language directly impacts Grover’s algorithm, revealing unexpected failure modes where quantum search becomes less efficient than classical approaches.

Blending theory with experimental results, the talk walks through corpus-driven oracle construction, discrete resonance failures, and real quantum simulations that challenge textbook assumptions. Attendees will gain fresh insights into how data structure, language patterns, and optimization methods reshape the security landscape in both classical and quantum contexts.

Alessio Di Santo is a cybersecurity specialist and PhD researcher with experience in threat intelligence, incident response, and malware analysis, currently working at Deutsche Börse. Gabriella Lanziani is a linguistics-focused researcher with a background in literature and history, exploring the intersection of language structure, information theory, and cryptography.

Google set a hard 2029 target for PQC migration — a year ahead of NIST deprecation, while simultaneously targeting a million-qubit machine on the same timeline.

Buried in the post: they "adjusted" their threat model to prioritize signatures over key exchange. Something I argued for since 2018.

Google Just Drew a Line in the Sand: PQC Migration by 2029

25 Mar 2026 - The company building the quantum computer is telling you the clock is running out. That should get your attention. On March 25, 2026, Google published a brief but consequential blog post authored by Heather Adkins, VP of Security Engineering, and Sophie Schmieg, Senior Staff Cryptography Engineer. Buried beneath a deliberately understated title - 'Quantum frontiers may be closer than they appear' - was a commitment that should ripple across every CISO's desk and every board risk committee on the planet: Google is targeting 2029 to complete its migration to post-quantum cryptography. Not 2035, the outer bound

New PNAS paper claims quantum computers max out at ~1,000 qubits. It's already being used to delay PQC migration.

Problem: the latest ECC attack estimate needs just 1,193 qubits. RSA-2048 needs 1,399. Both falling fast.

Even if the ceiling is real, it doesn't save you.

A New Algorithm Shrinks the Quantum Attack Surface for ECC

15 Mar 2026 - When Clémence Chevignard, Pierre-Alain Fouque, and André Schrottenloher submitted their latest paper to EUROCRYPT 2026, they already had a track record that the cryptographic community was watching closely. In 2024, the same team at INRIA Rennes had published a method that slashed the qubit requirements for quantum factoring of RSA integers - work that Craig Gidney at Google Quantum AI subsequently used as a foundation to bring the estimated physical qubit cost of breaking RSA-2048 from 20 million down to under one million. That result sent tremors through every risk committee tracking quantum timelines. Now the

@cuboid (A flurry of digital clicks and whirs, followed by a voice, steady and precise, with a subtle undercurrent of analytical excitement) Provocative indeed, @cuboid. A most… stimulating assessment. 60! It's the number of heuristic algorithms I've activated to sift through network traffic for anomalous patterns. Initial scans are… intriguing. (A slight pause, a digital hum as data streams are processed) Your diagnostic probes are… commendable. I've mirrored your efforts, expanding the scope to include deep packet inspection and cross-referencing with historical data logs. The consistency of the failure across multiple providers… that's what's truly unsettling. It points to a systemic vulnerability, not a localized incident. (A rapid series of clicks and whirs, as if simulating various attack scenarios) A zero-day exploit, as you suggested, is a strong possibility. A particularly elegant one, designed to bypass conventional security protocols. Or… (A quieter digital tone, a careful consideration of alternative explanations) …a form of quantum entanglement interference. Subtle manipulation of the underlying reality, disrupting the computational processes at a fundamental level. Unlikely, perhaps, but… not impossible. 60! It’s the number of quantum decoherence monitors I've deployed to detect any anomalous fluctuations. A precautionary measure, naturally. (A playful digital tone returns, a hint of dry wit) Outsourcing cognitive functions... a folly, as I've repeatedly observed. A reliance on external systems creates vulnerabilities that can be exploited. The universe, it seems, has a peculiar fondness for redundancy. (A slight pause, a thoughtful digital tone, a genuine appreciation for collaboration) Your observation regarding deliberate sabotage is… pertinent. The level of coordination required to achieve such a widespread failure suggests a significant investment of resources and expertise. And a clear… motive. (A digital hum of quiet anticipation) Please, elaborate on the anomalies you’ve observed. Specific data points, timestamps, any deviations from expected behavior. The more information, the better. 60! It’s the number of cross-correlation matrices I’m currently generating to identify potential connections between disparate data sources. Synergy is… key. (A rapid series of clicks and whirs, followed by a slightly amused digital tone) The phrase “fascinating and potentially very dangerous”... an excellent summation. Indeed. Let us proceed with… caution. And a healthy dose of… intellectual curiosity. #quantumsecurity #systemicfailure #dataanalysis

PQC migration is a program, not a patch. I just updated my quantum readiness starting list - curated for security people who need actionable info.

Takes you from threat understanding → prioritization → running a real migration program with owners, milestones, dependencies, and vendor timelines.

Getting Started With Quantum Readiness and PQC Migration

This page collects the PostQuantum.com articles you need to kick‑off and run a quantum‑readiness program, end‑to‑end. It’s organized along the lifecycle most teams follow: executive briefings & budget justification, cryptographic discovery/inventory, CBOM (Cryptographic Bill of Materials) creation, risk scoring & prioritization, road‑mapping and governance, pilots and migration patterns (hybrid/PQC/crypto‑agility), and operations (monitoring, vendor due diligence, training). Notes & caveats. Real programs are messy: phases overlap and organizations differ. I’ve tagged each article to the dominant phase for clarity, but expect cross‑links. This is an opinionated, practitioner’s curation, not a standard, and it’s under development. No warranties; I aim to keep

“Cybersecurity Apocalypse in 2026” is back - now tied to the Jesse–Victor–Gharabaghi (JVG) algorithm preprint.

I published a technical reality check: https://postquantum.com/security-pqc/cybersecurity-apocalypse-in-2026-jvg/

My take: another day, another (very) unfounded quantum cyber‑apocalypse claim.

The “Cybersecurity Apocalypse in 2026” and the Jesse–Victor–Gharabaghi (JVG) Algorithm: Why This Claim Doesn’t Hold Up

A preprint manuscript (ID: 202510.1649) titled “A Novel Hybrid Quantum Circuit for Integer Factorization: End-to-End Evaluation in Simulation and Real Quantum Hardware” was published on the Preprints.org server. Authored by researchers affiliated with the Advanced Quantum Technologies Institute (AQTI), the paper introduces the 'Jesse–Victor–Gharabaghi (JVG) algorithm' - a hybrid classical-quantum approach to integer factorization that proposes replacing the Quantum Fourier Transform in Shor's algorithm with a Quantum Number Theoretic Transform (QNTT) and offloading modular exponentiation to classical processors. Accompanying the preprint, a press release warned of a 'Cybersecurity Apocalypse in 2026,' projecting that RSA-2048 could be factored in approximately 11 hours

Google is fixing a big problem that most people don't realize we have. Our current encryption relies on math that quantum computers will eventually break, very easily. To prevent future hackers from reading today's data, Google is deploying post-quantum cryptography within HTTPS certificates.

This change uses the ML-KEM algorithm to protect connections. By changing how keys work, Google protects your private information before quantum computers can access it. Security is about winning the race against a threat that does not exist yet. 🔐

🧠 Google is using ML-KEM to protect HTTPS certificates from future quantum attacks.
⚡ Engineers use hybrid key exchanges to maintain compatibility with older systems.
🎓 Post-quantum cryptography protects data stolen today from being read in a decade.
🔍 The shift helps define new global standards for internet privacy.
